To see The Shouting Man you will have to step back from the computer screen (about ten feet should do the trick).
The photograph is of part of a Yew tree with the sun filtering through the dense leaf canopy highlighting just a small portion of the patterned bark. There are many other ‘creatures’ and faces within the picture, see if you can spot them.
The processing, reshading, recolouring etc. was done in PSP and colour/light balancing in photoshop elements.
